SAP -SPOUT.

SPECIFICATION forming part of Letters Patent No. 764,324, dated July 5, 1904. Application filed June 21, 1902. Serial No. 112,679. (No model.)

To (1,7 5 whom it may concern.-

Be it known that I, J AMES F. WARNER, a citizen of the United States, residing at Essex, in the county of ()hittenden and State of Vermont, have invented new and useful Improvements in Sap-spouts, of which the following is a specification.

My invention relates to improvements in sap-spouts, and pertains more particularly to those used in maple trees for drawing the sap therefrom.

The object of my invention is to provide a sap-spout which is adapted to obtain the greatest amount of sap from a hole of predetermined size.

A still further object of my invention is to provide a spout which will avoid the breaking and mashing of the bark around the opening, and thus prevent the decaying of the trees, thus lengthening the life ofthe trees and cansing the trees to give better results after successive tapping.

A still further object of my invention is to provide a simple, cheap, durable, and more effective sap-spout.

In the accompanying drawings, Figure 1 is a perspective view of my sap-spout. Fig. 2 is a side view showing the spout in the tree. Fig. 3 is a top plan view of my spout within the tree. Fig. Lis a side view of aslight modification.

Referring now to the drawings, A represents the portion of the spout which is outside of the tree and may be of any form, but preferably of that form shown in the drawings. The upper portion in this form is cut away at a and is provided at its extreme outer end with the drip-tongue a The said portion A is provided with a downwardly-extending hook B, by means of which the bucket is supported; but this could be left off, as it forms no part of my invention. Above said hook is an upwardly-projecting member 6, which aids in the withdrawing of the spoutfrom the tree. Adjacent said hook and projection there is an enlarged portion O, which rests within the opening in the tree, to be hereinafter more fully described.

The said enlarged portion commences to taper from the point e and tapers very gradually to the point 0, where it is provided with the elongated outwardly-reduced portion D. The said spout has a centrally-extending opening extending through the entire length thereof and through which the sap may flow from the opening. In order that the spout may be firmly held within the auger-hole and at the same timeallow the free liow of sap from all of the grain that has been cut by the boring of said hole, 1 provide opposite sides of the said outwardly-red uced portion 1) with laterally-extending horizontal elongated fins .l), which are of a length to extend out on a line even with the enlarged tapered portion, so that when the spout isdriven home the said lins will engage the sides of the hole, and thus lirmly hold the spout within the tree. It will be readily seenthat by having the lins on the sides they will engage the grains of wood on the sides of the opening that have not been severed, and as only the grains that have been severed issue sap the flow of sap is not in the least interrupted, as it will flow only from the top and bottom of said opening.

The portion O being tapered, as clearly shown, when the spout is driven home it is wedged within the opening; but at the same time the taper is so gradual that it will not break the outer or inner bark of the tree, but will completely close the opening, so that the sap cannot flow therefrom around the spout, but will flow through the opening in the spout. The tapered portion is such that no portion thereof will engage the walls of the opening beyond the bark, and thus the sap from all of the grains of wood is allowed to flow within the opening and find its way back and out through the opening in the spout. I also provide the spout with the tapered beading or circular flange F, which is adapted to engage the outer portion of the opening and more securely close the opening around the spent, so that the sap is less liable to flow or leak out; but said beading or flange is tapered, as clearly shown, and thus will not break or tear the bark around the opening.

Having thus described my invention, What of the reduced rounded portion and the outer I claim, and desire to secure by Letters Patedges of said fins in a line with the outer end ent, is of the tapering plugging portion.
